Abstract

PT. Chandra Asri Petrochemical Tbk. is a petrochemical company that experienced bag defects in the process of bagging polypropylene products exceeding the tolerance limit. The company sets a maximum bag defect limit of 0.028% of bagging production capacity. This study aims to control quality by calculating the sigma value of defect types and providing suggestions for improvement based on the factors causing defects. The method used is Six Sigma with DMAIC (Define, Measure, Analyze, Improve, Control). The analyzed data is bagging and bag defect production data for the period April 2023 to March 2024. The results showed that the percentage of bag defects was reduced from 0.051% to 0.034% after improvement. After improvement were carried out there was no data that was outside the control limits, and also the sigma value increased from 5.08 to 5.19. The main causes of bag defects are poor bagging machine maintenance, operators who are less focused and thorough, and implementing different SOPs. The company's proposed improvements include improving bagging machine maintenance, creating an SOP that requires checking seal results periodically, and updating the SOP

Abstract

Non-Oil and Gas Exports play an important role in Indonesia's economy, including in Banten Province. This is due to the significant contribution of non-oil and gas exports to the country's foreign exchange earnings. The fluctuations in demand for non-oil and gas exports in the international market can be used as a forecasting basis to determine the balance between production and demand for non-oil and gas products in the international market. The aim of this research is to obtain forecasts of non-oil and gas export values from April to December 2024. The data used in this study is monthly time-series data of non-oil and gas export values from January 2020 to March 2024. The forecasting method used is the Box-Jenkins ARIMA (p, d, q) model. The forecasting results produced the best model, ARIMA (4,2,0), with the equation is  with an MSE value is 11,581.7. Non-oil and gas exports in 2024 showed fluctuations from April to December 2024, with each forecasted value as follows: April at 1,033.94, May at 1,025.74, June at 1,075.72, July at 1,069.83. August at 1.113,51, September at 1059,30, October at 1.113,33, November at 1.133,85, and December at 1120,29
